Spinning logo

Here's my attempt at a Hydra version of the animated GIF from this thread in the Propeller forum, http://forums.parallax.com/showthread.php?p=669987.

Requirements: Hydra, NTSC TV.

A brief video of it in action: www.finitesite.com/mpark/spinning_logo_001.wmv

The conversion to Hydra colors and screen size was done mechanically without a lot of finesse. I think the quality could be much improved if we can just convince Clemens to do yet another version, this time with a Hydra-optimized palette and a funky aspect ratio...

I'd be interested to hear how it looks on other people's TVs. I've only seen it on my little LCD.

Very nice! I'm glad I thought of this. I'm surprised that no one else did before me...

Also tested it on my own Hydra with a 5" LCD screen: www.youtube.com/watch?v=NwOQJOwH9i0

The text is a little close to unreadable though. But nevertheless, it is still.

My biggest concern here is that this logo, which is meant I believe just to be a "splash screen" for other programs, by itself takes up almost all of the RAM on the Prop, leaving only 396 free longs for your own code.

While I really don't know much about this, since the image is the same (as far as I know) with the exception of the propeller on the hat itself, couldn't you just animate that, instead of having screen-sized relatively similar bitmaps?

I'm going to use a screen that has a built in SD card for image storage. This will take the load off of the Prop.

So you'll be playing it via the screen, or pulling images from the SD card and displaying them using the Prop?

As I understand it, I send the LCD controller a command to access the images from the SD card. The LCD controller's built-in ARM microcontroller takes care of displaying it.

The program actually does animate only the propeller area of the screen. In the archive you'll see eight files named prop64x20*.dat; these are the 64 pixel by 20 pixel propeller frames.·The screen itself is 128 x 160.

Other than that, I agree about the memory issue. I could have cut the propeller frames down even more, but I doubt it would have made that much difference. I never claimed this was useful!

Back in late march/early april I was going to create an animated·5 color spining beanie logo for·my Embedded Systems Conference demo, but I ran out of time to complete it and more important things always come up. Some of the tiles I created for it are still in my demo program posted in the thread regarding ESC

Nice!
Too bad I don't have a Hydra. I tried to "convert" it for the demoboard with the usual adjustments, but somehow it didn't work. Besides I have a PAL TV and none of the HYDRA Drivers seem to have a PAL mode so I couldn't see the colors anyway.

... and don't forget Beau's beautiful 3D logo. Ok in this case the complete hat is spinning, not just the propeller.
